Definitions

  • the invention relates to a subframe in the chassis area of a two-lane vehicle, with two spaced-apart longitudinal members, at least one cross member connecting them and two intersecting in plan view of the road and interconnected at the intersection, strut-like stabilizing elements, which are each supported between the two side members.
  • strut-like stabilizing elements which are each supported between the two side members.
  • Such a subframe may, for example, or preferably be used as a so-called.
  • Front axle of a motor vehicle Such front axle carriers are also said to have good properties, i.e., a vehicle crash. in particular have sufficient rigidity.
  • a subframe with a so-called thrust field is disclosed, which represents a planar structure which is inserted between the longitudinal members and the cross member. Such a planar shear field can transmit essentially tensile forces and shear forces.
  • the solution to this problem is for a subframe according to the preamble of claim 1, characterized in that the two stabilizing elements, including the connecting portion are formed by a single hollow body, which formed essentially by two in a plane parallel to the road surface in a force-transmitting manner interconnected cup-shaped structures is.
  • the cup-shaped structures are sheet-deep-drawn parts, which are welded together to form the hollow body.
  • FIGS. 1-4 show a preferred embodiment in a simplified manner.
  • 1 shows the (spatial) view of a subframe according to the invention with mounted hollow body, which forms the stabilizing elements and their connection area, while in FIG. 2 the hollow body alone and in FIG. 3 the so-called upper shell and in FIG Lower shell, from which this hollow body is composed, are shown in a similar view obliquely from above to the roadway.
  • Two mutually spaced longitudinal beams 1 and a cross member 2 interconnecting these form a subframe of a motor vehicle which acts as a so-called front axle carrier, whereby two strut-like stabilizing elements intersecting one another in a cross-over point between the two longitudinal beams 1 are supported and joined thereto their ends are preferably releasably secured to the respectively facing longitudinal member 1.
  • These strut-like stabilizing elements according to the present invention are not independent components and are therefore marked for differentiation from those marked with the letters A, B, while the letter "X" indicates their "fictitious" crossing point.
  • Each of these shell-shaped structures 3a, 3b has - in top view of the road - the basic structure of, for example, in the already So-called struts cross on, so four of a so-called.
  • Connecting region ( environment of the intersection point X) projecting arms, the two intersecting diagonals with respect to this connection area mentioned DE 10 2005 038 182 A1 or in Figure 2 of the aforementioned DE 28 41 796 form and extend beyond this connection area, said two diagonals form the already mentioned strut-like stabilizing elements A, B.
  • the shell-shaped structure 3a shown in FIG. 3 acts as a so-called upper shell of the hollow body 3, while the shell-shaped structure 3b shown in FIG. 4 is its so-called lower shell.
  • the upper shell 3a (see Fig.3) is arched towards the viewer and thus represents a convex spatial body
  • the lower shell 3b is curved away from the viewer and thus represents a concave spatial body.
  • the two shell-shaped structures 3a, 3b are now joined to one another or overlapping one another in order to form the (or a closed) hollow body 3.
  • This assembly in a plane substantially parallel to the road surface is such that a force transmission between the two shell-shaped structures 3a, 3b is possible, preferably by welding the two shell-shaped structures 3a, 3b, which in turn are made by deep drawing of a steel sheet metal parts ,
  • the hollow body 3 thus formed is capable of transferring relatively high compressive forces in the direction of said diagonal or stabilizing elements A, B between the two longitudinal members 1, advantageously at a relatively low weight. Furthermore, this hollow body 3 is relatively easy to manufacture and can be as a prefabricated component easily and quickly attached to the side rails 1, preferably via screw, it should be noted that quite a variety of details may be designed differently from the above explanations, without the To leave the content of the claims.

Abstract

L'invention concerne un châssis auxiliaire situé dans la région du train de roulement d'un véhicule à deux lignes, avec deux longerons espacés l'un de l'autre, au moins une traverse reliant ceux-ci ainsi que deux éléments de stabilisation en forme d'entretoise, se croisant dans une vue en plan sur la chaussée et assemblés l'un à l'autre au point de croisement, qui sont chaque fois supportés entre les deux longerons, dans lequel les deux éléments de stabilisation y compris leur région d'assemblage sont formés par un corps creux unique, qui est formé essentiellement par deux structures en forme de coque assemblées l'une à l'autre de façon à transmettre des forces dans un plan parallèle à la chaussée. De préférence, les structures en forme de coque sont des pièces de tôle embouties, qui sont soudées l'une à l'autre pour former le corps creux.
